Application filed February 13, 1900. Serial No. 5,072. (No modell) To @ZZ whom it may concern:

Be it known that I, CHARLES A. BRYANT, a citizen of the United States, residing at Wakefield, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Tack-Fastcned Buttons, of which the following is a full, clear, and exact description.

This invention relates to that class of tackfastened buttons in which an anvil is secured in the bottom of the button-shank and is adapted to upset the point of the tack, and thereby to engage the button with the tack and the garment or other article to which the button is applied. A button such as described is covered in the patent of the Scovill Manufacturing Company, assignees of Alfred J. Shipley and Theophilus R. Hyde, Jr., No. 598,021, dated January 25, 1898.

The present improvement consists in a tackfastened button having an anvil made of a piece of metal folded upon itself one or more times, one of the folds containing the tackopening and constituting the base or iiange of the anvil and the other fold being crowned to afford means for upsetting the point of the tack and to constitute a chamber within which the point of the tack is upset, concealed, and retained.

In the accompanying drawings, illustrating my inventiomin the several figures of which like parts are similarly designated, Figure l is a plan view of a blank which may be used in the formation of an anvil in accordance with one form of my invention. Fig. 2 is an elevation, and Fig. 3 a vertical section, of an anvil formed from a blank like that shown in Fig. l. Fig. 4 is a vertical section of an openface button having the anvil of the present invention secured therein by lateral indentations or prick-points. Fig. 5 is a vertical section of one form of covered or closed-face button, in which the lateral indentations or prickpoints or other means for securing the anvil in the bottom of the shank may be used or omitted at pleasure. Fig. 6 is a vertical section illustrating the manner of securing a button of the character shown in Fig. i to a piece of fabric or a garment by means of a 5o tack. Z is a vertical section of a button similar to that of Fig. 4, but substituting an annular constriction for the lateral indentations. Fig. 8 is a vertical section of an openface button, in which the bottom of the shank and of the anvil. are inclined upwardly and inwardly. Fig. 9 is a plan view of a rectangular blank from which an anvil may be made. Fig. 10 shows the first fold to which the blank of Fig. 9 is subjected, and Fig. ll is a Side elevation of the finished anvil. Fig. l2 is a 6o plan view of a double-fold blank of rectangular outline. Fig. 13 shows the first folds of such double-fold blank. Fig. 14 is a vertical section of a closed-face button containing an anvil made in accordance with Figs. l2 and 13.

In producing one form of my anvil I use a blank such as shown in Fig. l, having the circular portions a and b, connected by an integral portion c. The portion a is perforated 7o at d for the passage of the tack, and the portion b is crowned upwardly, as illustrated in Figs. 2 and 3, by drawing or stamping or other processes and is bent over upon the portion a, the integral portion c serving to keep the portions a and b rigidly united. As shown in Fig. 3, the portion a constitutes the base or bottom iiange or washer of the anvil, while the portion h incloses a chamber above the base d and serves to turn over or upset 8o the point of the tack and to inclose such upset point, while its escape is resisted by the portion a. The portion a serves also as a reinforce for the bottom of the shank of the button.

The anvil constructed as described maybe applied to a button in any of a great variety of ways. For example, as shown in Figs. et and. 6, the button c may have a central depression e', constituting the hub or shank of the button, and the anvil (designated f) may 9o be arranged Within said shank, with its baso a resting upon the bottom g of the shank and held therein against displacement before the button is applied to a garment by a number of lateral indentations or prick-points h in the shank, or, as shown in Fig. 5, the anvil f may be arranged in the bottom of a central depression t' in the back shell or colletj of a covered or closed-face button and se cured. therein solely by means of the faceu roo plate 10 or by such face-plate and somesort of lateral displacement of the shank, or by the latter device only. As shown in Fig. 7, the anvil f may be secured in the bottom of the shank by means of a circumferential or annular depression Z-that is to say, the shank may be'k constricted-.about `theanvil and'above lits base.

As shown in Fig. 8, the base m of the anvil n may be crowned inwardly, as may also the bottom o of the shank of the button. This feature is not, original, however, withV this invention.` As shown in Fig. S, vthe shank: of the button is constricted'at secure the anvil in place.

Instead of using blanks having circular ends I may use a rectangular blank, as shown in Figs. 9 to 14, and, as shown in Figs. 9, 10, and 11', such a rectangular blank may be fold= edonce upon itself, one portiomr, containing the tack-opening sand the other portion, t, being crowned, as at u, to form the chamber in whichthe tack-point is upset and-retained. As shown in Figs. 12 to 14, a rectangular blankmay be folded upon itself twice, and in such case o is thebase, having the tackopening o', wis the intermediate portion,con

taining a larger openingw, which may be considered as a portion of the Wall of the chamber'forthe reception ofthe upset point of the tack, and the third portion m has'the domed or crowned portion against which the point of the tack is upset and which cooperates with the intermediate and' base portions to form a chamber for the reception and retention of the upset tack-point. As shown in Fig. 14, this angular anvil is adapted to be received withinV a button of the closed-face variety, and itis obvious it might be applied', at least in someinstances; to anY open-face button. It' might be necessary in some instances to enlarge the central depression which forms the 'shank or hub to receive the angular anvil.

It iswithin my invention also to make the anvil from a rectangular blank and then trim pin orderto crownediand the other' perforated a-ndconsti-V tuting the? base through which passes the tack into and to be upset by and within the .crowned portion. It is to be observed also f that my invention is not limited to any of the specified means for securin g the anvil in place lin the button.

The drawings are exaggerated inorder the more plainly'to'illustrate the principle of the invention.

What I claim is- 1. A tack-fastened button, having-.ananvil' composed of aperforated base, and aninte'- gral crowned portion, thefbase and crowned` portion being folded together, substantially as described.

2. A tack-fastened butt-on, having-ananvil comprising a base perforated for the entranceof the point of the tack, anda crownedl portion for upsetting the point of the ,tack and within whichand between it and the base the said upset point is contained, the said base and crowned portionbeing integral and folded one upon the other, substantially'as described. y

3. A tack-fastened'button, having-an anvil comprising a circular base perforated iorftfhev entrance of the point of the tack, andY al my hand this 10th day ot` February, A. D. 1900.
